| Abstract: | By use of wavelet power spectrum analysis and discrete wavelet transform, the periods and characteristics of J
2 time series of GRACE time variable gravity models from CNES/GRGS、CSR、GFZ are analyzed and extracted, and then they are compared with the corresponding results of
J2 time series from SLR tracking data. The resalt shows that, the seasonal variation of J2 time series from SLR is clearer than that from GRACE. In addition,the signal for 161 days is mexed into GRACE J2 time series,which is caused by ocean tide model error in the S2 solar tide |
